Pin assignment or pin out
Generally speaking, the pin assignment or pin out can be like this (4 pins to be connected):
| OBD2 female | Signal | J1939 female | J1939 male |
| 4 or 5 | Ground | A | A |
| 16 | Battery | B | B |
| 6 | J1939, CAN-H | C | C |
| 14 | J1939, CAN-L | D | D |
Sometimes, the pin assignment or pin out can also be like this (6 pins to be connected):
| OBD2 female | Signal | J1939 female | J1939 male |
| 4 or 5 | Ground | A | A |
| 16 | Battery | B | B |
| 6 | J1939, CAN-H | C | C |
| 14 | J1939, CAN-L | D | D |
| 2 | J1708-H | F | F |
| 10 | J1708-L | G | G |
The 6-wire cable also includes wiring for the J1708 lines. If you do not need the J1708 wires, it is better not to connect them as sometimes the added lines can interfere with the operation of some GPS trackers.
The pin assignment or pin out can also be customized according to your drawings.
Application
This cable is used to connect telematics, fleet management devices or trucking technology devices such as GPS Trackers or ELDs (Electronic Logging Devices) to commercial vehicles that have the J1939 9-pin round Deutsch ports.
This cable will also allow OBD2 diagnostic devices or scanners or fault code readers (with the appropriate software) to connect to the round J1939 connector. Bear in mind that most OBD2 software and scanners are based on reading PIDs, which are single parameters. J1939 is a PGN based protocol, where each PGN contains multiple parameters. Your diagnostic or scanner tool must be able to handle PGNs if it is to work with this cable.
